AUTOMATIC CONEAND TUBE GAUGE.

Application filed February 18, 1922. Serial No. 537,595.

To all cti/0m t may concern.' Y

Be it known that I, MICHAEL J. SHEEHAN, a citizen of the United States, and resident of New Bedford, in the county of Bristol and Commonwealth of Massachusetts, have inf vented certain new and useful lmprovements in Automatic Cone and Tube Gauges; and l do hereby declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art :to which it appertains to make and use the same.

The invention relates to a gauge attachment for cone and tube winding machines of' standard make, that will be effective in actuating the stop motion and arresting the operation of the winding machine when the cone or tube of thread or yarn has reached the desired diameter, the gauge device prefer-ably comprising a rod-like element adapted to be attached to and carried b-y a member of the winding machine having a movement commensurate with the increase in diameter of the cone or tube, as, for example, the cone or tube holder' or the door which carries the lthread guide, according` to the particular type of winding machine employed, said gauge rod having thereon an adjustable detent adapted to engage a suitable member ofthe stop motion, when the cone or tube has been built up to th-e desired size and'thereby move the gauge rod a commensurate distance.

The invention is illustrated in the accompanying drawings, in which:

Fig. l is a fragmentary perspective View of a cone or tube winding machine having the gauge device attached thereto;

Fic". 2 is a vertical elevation of the bar member of the gauge;

Fig. 3 is an edge elevation thereof, showing the detent in position; and

Fig. 4 is a plan view of the gauge showing the bar in section.

The invention is illustrated in Fig. l as applied to a so-called universal winding machine, of which a single cone or tube winding unit is shown, the same involving a cone holder l0, friction drive roller, thread guide, tension and stop motion. As illustrated, the stop motion includes a pivoted member 11, which is normally actuated upon the breaking of the thread or the slacking of the tension thereon, by swinging the member 11 to the position shown in dotted lines. These elements are characteristic of machines of this general type and require no specic ydescription.

In operating machines of this general character, it has heretofore been necessary for the attendant to stop each particular cone or tube to measure the diameter thereof by a i hand gauge, which resulted in a material loss of time both to the operator and the machine, and, in case a particular cone or'. tube was over-wound, necessitated the unwinding and rewindng thereofwith a possible damage to the thread oryyarn. The stopping `of the winding of any one of the cones or tube, in order to measure the diameter thereof, also damages the thread by causing an undue strain thereon,inasmuch as the manual stopping means does not release the tension device. y

The present invention is intended to obvi? ate these difficulties and objectionsto ma chinos of this type, and to provide means for stopping the individual winding units when the cone or tube of thread wound thereon'has reached thedesired vpredetermined diameter. As illustrated' in they drawings,` the attachment constituting the present invention includes a bar or strip of metal or other suitable material,'1, provided. at one end with means for attaching it to a member of the winding machine which has a movement commensurate with thev increase in diameter of the cone kor tube, in the instant machine, said member constituting the cone holder' l0. As illustrated, the means for attaching the bar 1 to the coiie'holder l() may conveniently take the form of a loop 5 formed in the end of the bar, provided with a bolt and nut to clamp the loopy firmly about the cone holder and hold the bar in properly adjusted position. bar is provided with a series of openings 9 adapted to receive thereduced end 7 of an pin 6 passing through a hole in the reduced end 7 of the detent.

The lower end of the The angularly disposed arm of the detent projects under the trip element ll of the stop motion so that when the bar member vl is raised lby successive steps, due to the increase` in diameter of the cone or tube, the said arm of the detent engages the under face of the trip device l1, as shown in dotted lines in Fig. l, and actuates the stop mechanism,v`v

which immediately arrests the operation of the machine. By adjusting the detent 2 in the proper hole 9 in the rod l, it Will be apparent that the rod and detent Will constitute an adjustable gauge which will accurately determine the diameter of the tube or cone, and stop the machine when the predetermined diameter has been reached.

Vhile th-e particular form of the attachment illustrated has been found effective and convenient, it Will be understood that the invention is in no sense limited thereto, as the construction of the gauge, the manner of attaching the same to the movable part of the Winding machine, and the means for adjusting the detent on the bar, may be varied at Will.

It is also to -be understood that the device is applicableto any of the standard type machines for Winding cones or tubes, which involves a movable member of each Winding unit, the movement of Which is commensurate With the increase in diameter of the cone or tube, and to Which member the gauge device can be rigidly attached. For eX- ample, in another type of the universal machine, there is employed a door carrying the thread guide, which door moves commensurately With the increase in diameter of the cone or tube, and in this type of machine the automatic gauge` as described is rigidly at taehed to any suitable portion ot' the door element.

vThe particular advantages of the invention as described are the insurance of substantial uniformity of diameter of the cones or tubes, facility ofadjusting the gauge to produce cones or tubes of any desired diam-r eter Within the range of the machine, avoid` ance of yundue strains and unequal tension onv the. thread as the same is being laid up, and to materially increase the output of a given machine by avoiding the necessity of hand gauging and consequent stoppage of the machine.
